Experiment, eh?

We have the staging tree because it's a widely acknowledged belief that kernel code in the tree tends to improve over time compared to code that's sitting out of the tree. Are you disputing that belief?

If you don't dispute that, what makes you think the same effect doesn't apply to code that looks like Linux code and is developed the same way but runs in userspace?
